The family of a teacher murdered by a schoolboy have begun a High Court challenge against a coroner's decision not to call other pupils as witnesses at an inquest into her death.
A judge in London will hear the judicial review action brought by Ann Maguire's husband Don, children and nephews.
Today's hearing before Mr Justice Holroyde follows an earlier ruling that the family had an "arguable" case which should be fully aired.
Mrs Maguire, 61, was stabbed to death by a 15-year-old pupil as she taught a Spanish class at Corpus Christi Catholic College in Leeds in April 2014.
Will Cornick was later sentenced to life by a judge who ordered that he must serve at least 20 years, and warned that he may never be released.
An inquest into Mrs Maguire's death is due to take place before a jury at Wakefield Coroner's Court in November.
